CAR SEAT AND BACK.

SPECIFICATION forming part of Letters Patent ]}lo.'237,7f23, dated February 15,1881.

' Application filed December 3, 1879.

- To all whom it may concern:

This invention has reference to improve-v ments in the construction of car seats and backs by which not only a more elastic and neater seat is obtained, but also the covering protected and the upholstering, as well as any part thereof, more quickly repaired, so that the cars need not be too long retained or taken out of their regular trips.

The invention consists, first, of a car seat orback made of two separable sectionsa supporting base portion and a removable top section.) The upholstered portion of the top section is supported by connected s iral main springs, which are stifi'enedby auxiliary double side springs of the base-section. The removable top section is composed of a side frame and an upholstered covering, and screwed to the base-frame; Metallic corner stays are screwed to the base and top sections and serve to protect the corners of the seat.

In the accompanying drawings, Figure 1' represents a top view of myimproved car seat or back, (shown partly in section, and with a portion of the covering removed for exposing the interior construction and Fig. 2 is a vertical transverse section of the same on line 00' m, Fig. 1.

Similar letters of reference indicate corresponding parts. 7

A in the drawings represents the base .portion, and B theupper or top portion, of my improved car seat or back. The base portion A is made of .aarectangular open frame, a, of the required size, and of a stiff pasteboard bootn the pasteboard bottom b. are supported the spiral cushioning-springs 0, which are either of the common form with circular top and .1 bottom portions or made with rectangular topand-bottommo'rtions, as desired. The

main springs 0 are linked together at their bases and tops, and re-enforced against side pressure by side springs, D, which are secured at their lower ends to the frame a and to the base portions of' the springs O, and at springs O, can be pressed inwardly.

and are cushioned by spiral spring portions d,

so that a double springaction at the top and bottom is obtained when the main springs give to the pressure exerted thereon by the weight of the sitter. They also assist in reenforcing the main springs and in returning them to their normal position. The lower ends of the auxilary springs D are secured by staples to the inner beveled face of the baseframe a, so that only their upper ends, which are connected to the top parts of the main Both the lower and upper coils, d d, of the auxiliary springs or stays D throw their resistance in upward direction against the upholstered. top and the weight resting therein. They return the upholstered top to its former position when the Weight is removed.

The base-frame forms, with the main springs O and side springs, D, the base portion of my seat or back, to which the upper or top section, B, is rigidly secured by screws. The top section, B, is made of a side frame, B, which is of slightly smaller size than the base frame, a, so that the latter projectssomewhat,

and protects thereby the plush or other covering of the seat against abrasion. The upholstered top B is attached to the side frame, B, and supported at the interior by-the main springs C, and at the edge by a stuffed cord, B which is placed into a concave seat of frame B, as shown in Fig. 2.

The seat may be readily restufled or the covering replaced when worn out by simply removing the seat'and then detaching the upper seat-section from the base-section. This facilitates repairs and overcomes the difficulties and delays at present experienced in the lrepairing of the seats, as thereby such repairs can be attended to at a considerable saving of time and expense. I

The top and bottom sections of the seat are furthermore connected by corner stays or facin gs E, of quadrantal cross-section, which are screwed to the seat-sections, the lower parts of the corner stays being set into recesses act the base-frame a. The corner-stays E',cover and protect the meeting edges of the covering, and impart an ornamental and finished appearance to the seat. They do not extend entirely up to the top of the seat, but stop short below the bulge formed by the cord 13", as shown in Fig. 2. By unscrewing the connecting-screws of the top and bottom sections, and also the screws by which the'corner-stays are A attached to the base-frame, the top section latter being secured at both ends to the main springs O, of a removable upholstered top section, 13, connected, substantially as described, to frame A, substantially as set forth. 2. In a carvseat or back, the combination,

with the main springs supported. on a'suitable base-frame, of double re-ent'orcing side springs, the lower portions of the latter being secured to said frame and to the main springs, while the upper ends of said side springs are secured to the top of said main springs, substantially as set forth.

3. In car seats and backs, the combinationvof base portion A, having corner recesses 0,

with a removable upholstered top section, B,

screwed to the base portion A, and with pro-- tecting corner stays E, which are set into the recesses of the base portion, extended over the corners of the top section, and attached to 1 both base-frame and top section, substantially as specified.

In testimony that I claim the foregoing as my invention I have signed my name,in presence of two witnesses, this 29th dayofNovember, 1879.
